Lymph is a fluid rich in protein, and it fills the spaces between cells and blood capillaries.
Lymph contains the followings.
-Fat Soluble Vitamins (Vit. A, D, E, F, and K)
-Dead Cells, Debris
-Bacteria and Viruses
-Inorganic Substances (coal, dust etc)
Lymph exists right under the skin. It is gathered and drains into lymph vessels, and it travels deeper in the body.
Lymph vessels carry lymph to the roots of the limbs, reach below the neck, then accompany the venous blood circulation on its journey.
Lymph nodes are located at several places in the lymph vessels. There are about 600 lymph nodes in the human body and about 160 are located in the neck area.
Lymph nodes filter and concentrate lymph. They are the site of replication of immune cells and store some substances that cannot be broken down or removed (coal, dust etc).
When excess lymph accumulates between the tissues, it disturbs the exchange of nutrients and waste products, oxygen and carbon dioxide. Proteins and immune cells cannot perform their functions. The metabolic situation is disturbed and the healing slows down.
This is why It is significantly important to have a good lymph flow.
